Westchester-area Councilman Mike Bonin will join hundreds of volunteers, with clipboards in hand, who will take to Los Angeles street corners starting Tuesday to conduct a citywide count of bicyclists and pedestrians.

Bonin will be stationed in West Los Angeles, at the corner of Bundy Drive and Idaho Avenue.

While there are plenty of figures about car trips, “very little is known about the rates of people walking or bicycling in Los Angeles,’’ Bonin said.

“For too long, our city’s focus has been on cars, and not on communities — despite the evidence that walking and cycling promote healthy lifestyles and reduce pollution and traffic congestion,’’ he said.

The Los Angeles County Bicycle Coalition and L.A. Walks will carry out the biannual count at 120 intersections throughout the city.

According to the 2009 count, bicyclists in Los Angeles numbered 14,000 and there were 62,000 pedestrians. In 2011, 15,000 bicyclists and 75,000 pedestrians were counted.

This year’s count begins with sessions from 7-9 a.m. and 4-6 p.m. Tuesday, and from 11 a.m. to 1 p.m. on Saturday.
